SEAT FOB,A FARM MACHINERY.

Application led September 10, 1921. Serial No. 499,651.

To all whom it may concern.'

Be it known that we, LORENZ KIsoR and RALPH W. HAMME'I'r, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have 'invented certain newy and useful Improvements in Seats for Farm Machinery; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

rlhis invention relates to a rotatable and resiliently supported seat, and particularly to such a seat designed for use on agricultural machines.

It is an obj ect of this invention to provide a seat structure by means ofwhich the seat is rotatably and resiliently sup orted, the `seat being mounted for forwar and rearward tipping movements in its various positions of rotation.

lt is a further object-of the invention to provide such a structure with resilient means whereby theseat will be cushioned in both its forward and rearward tipping movements in all of its various positions of rotation.

These and other objects and advantages of the invention will be apparent from the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which,

Fig. 1 is a view in side elevation of the seat;

Fig. 2 is a view in side elevation on an enlar ed scale, the seat proper being removed;

ig. 3 is a view in front elevation of the seat; land E Fig. 4 is a vertical section taken on the line 4 4 of Fig. 2.

Referring to the drawin s, .a seat proper is shown which will prefera ly be lformed of metal cast or molded to provide a comfortable shape and one having a pleasing appearance. It will be noted that the seat has a portion rising at the rear thereof so that the lower portion of the occupants back is supported. rIhis results in a rest for this part of the occupants body and prevents the fatigue usually arising when a flat seat 1s used.

The seat 1 issupported upon a plate and may be connected thereto by any suitable fastening means, .such as bolts or rivets.

The plate 2 has an approximately central lug 2& depend1ng from its underside which is received between opstanding ears 3 formed on another plate member 3, and said lug 1s sup orted between'said ears by a headed an nutted transverse pivot bolt l passlng therethrough and through said ears.

he seat and plate 2 are thus supported upon the bolt and guided by said lug, and ears for forward and rearward tipping movements. The plates 2 and 3 are also provlded, forwardly and rearwardly of their central portions, with projections adapted to receive and hold in place coiled springs 5 supported upon plate 3. rlhe plate 3 rests upon asupporting member 6 having spaced dependlng ribs on its lower portion arran ed to fit over a resilient supporting bar i w ich extends forwardly of the seat structure and will be supported at its lower end to the machine on which the seat is used.

The plate 3 is connected to the supporting member 6 and said supporting member is connected to the bar 7 by a headed and nutted bolt 8, the head of which seats on the plate 3 between the ears 3a. The plate 3 fits loosely about the bolt 8 and is thus rotatably mounted on the plate 6 into which belt 8 is threaded. The bar 7 may be provided with a plurality of holes so that the supporting member 6 may be secured in' various positions thereon.

From the described structure it will be seen that the seat is mounted upon the bar 7 and is resiliently supported by said bar. The seat is also arranged for forward and rearward tipping movements no matter in what position of rotation it may be located. The occupant of the seat can turn to any position about the center of the bolt 8 and the seat will still be cushioned 'in its forward and rearward tipping movements. The jolts and jars due to the movement of the machine will be absorbed by the resilient bar 7 and the occupant will also be relieved from jolts and jars due to his movement, by the springs 5. It will also be noted that the seat will normally occupy a horizontal postion and will be returned to such position, after its tipping movements, by the springs 5.

From the above description it is seen that applicant has provided a seat of simple and yet very efficient structure. The same can be readily applied to practically all standard types of farm machinery, and can be ad;

justed thereon to any desired position. The fact that the seat is secured to the supporting bar by a single bolt contributes greatly to the facility of its application and renders it an easy matter to transfer the seat from one machine to another.

It will, of course, be understood that lvarious changes may be made in the f orm, 'o1e tails and arrangement of the deV1ce w1th out departin from the scope of a pllcants invention, W ich generally state consists in the matter shown and described and set forth in the appended claims.

What is claimed is:

1. A spring seat for farm machinery having in combination a s ring bar, a member embracing and adjusta ly mounted thereon, a supporting plate rotatably mounted on sald member, a seat pivotally supported and guided on said plate Jfor forward and rearward tipping movements, and spaced resilient means on said yplate engageable by said seat in said movements.

2. A seat for farm machinery having in combination, resilient seat supporting means, a rotatable supporting means mounted theremames ment..

3. A seat for an agricultural machine having 1n combinatlon a curved spring bar, a member havmgmeans for securing the same in a plurality of positions on said bar, a plate rotatably mounted on said member, said plate having upstanding adjacent lugs disposed substantially centrally of its upper surface, a seat having a lug depending substantially centrally thereof disposed between said lugs and pivoted thereto by a horizontal pivot, and compression springs supported on said plate forwardly and rearwardly of said lugs adapted to be contacted by said seat.

In testimony whereof we affix our signatures.
